Q7. A researcher is interested in the relationship between the number of miles that a used car has been driven (denoted by mileage) and its selling price. Based on a random sample of 60 of a particular model of used cars, the following model was estimated: y=Bo+le+8 Where y is the selling price (in thousands of E's) and x is the mileage (in thousands of miles). Least-squares estimates are provided in the table below: Estimate Std. Error (Intercept) 17.49 0-48 mile 9 0.17 0.02 You are also told the following: 1" 20. -5\"): = 115.7 . 2(5). y)2 = 121.3 i=1 A. Interpret the estimated coefficient on mileage. (2 points) B. Test the null hypothesis that B1=0 against a two-sided alternative using a 5% significance level. (2 points] C. Calculate the coefficient of determination and interpret it in context. (3 points) D. Use the provided information to calculate ?=1(x5 .732 (3 points)
